. To all Iwhom it may concern:

Be it known that I, THOMAS UROMWELL ROBINSON, of St. Paul, in the county ot`Ramd' ner of arranging the .buckets upon and securing them to the arms, as hereinafter set forth. I obtain these results by the use of the mechanism illustrated in the accompanying drawings, in which- Figure I is an end elevation of a wheel; and Fig. II, a frontelevation ofa portion of a wheel, showing my improvements attached thereto. Figs. III and IV are detached detail views ofthe ordinary form and my improved form of bucket, illust-rating their action in entering and leaving the water.

A is the shaft, and B the hub or heath t0 which the arms O are attached in the usual manner. Upon eitherI side of the outer ends of each arm C angular blocks a are secured, -across which the buckets b are fastened by bolts c, as shown. By this means the buckets are arranged at'an angle to the arms, and leave the Water in a nearly upright position, (see Fi'gs. I and IV,) so that little or no clifting o, the water occurs,'whieh is an important advantage, as a very large percent-age of power is required to lift the large body of water above the buckets when set at a line parallel with arms C, as shown in lower view of Fig. IV.

I also claim a great advantage by arranging two buckets on each arm, as I thereby obtain double the number` of buckets as in the ordinary arrangement 5 or I can obtain the same Vnumber of buckets by using only one-half the number of arms.

Another advantage gained by attaching two buckets to each arm is, that a greater number of buckets are in the water at the same time, thereby increasing the power ot the Wheel wit-hout adding to its diameter.

By slanting the buckets they enter the Water in less time than by the old method, and retain their power or liold7 upon the water longer in leaving it.

What I claim as new is-. t

The combination and arrangement of the arms C,angu1ar blocks a, and buckets b, secured together bythe bolts c, substantially as 'set forth.
